[master] RFR: Add some inlining and avoid CAS for quick_enter for lightweight locking.

[Coleen Phillimore]

This is sort of a simple change to inline the code that decides to go to LightweightSynchronizer in case the call has some negative effects for performance sensitive code.  Avoiding the CAS in try_enter was the most helpful.  With perf, I found that the CAS had a longer stall than with the code without the OM world refactoring.  The OM world table is off for this comparison.
Tested with tier1-4, including some local changes to run tier1 tests with -XX:+UseObjectMonitorTable.
